The torch is designed for use with a power supply which senses coolant return flow to confirm that torch parts are
in place. If coolant return flow to the power supply is absent or insufficient the power supply will not provide power
to the torch. Coolant leakage from the torch also indicates that torch parts are absent or installed improperly.
E. Type of Cooling
Combination of gas stream through torch and liquid cooling.
